i am currently getting my tf 97 roadworthy and the horn isnt working. but i have checked the fuse box under the bonnet and there is no relay for the horn fuse.
any idea where i can purchase this or if anyone is wrecking their car and is looking to sell/get rid of some?

Wreckers.

Wreckers.

Yup, most wreckers down here won't even bother charging for them.
